Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).

llvm-svn: 181322

With this change, __internal_*stat always expect a "struct stat *" argument.
This avoids stat/stat64 caller-side confusion (sanitizer_common tests already
made this mistake), and allows the use of __internal_fstat() as a drop-in
replacement for libc's fstat().

llvm-svn: 181311

Some flags that are common to ASan/MSan/TSan/LSan have been moved to
sanitizer_common.

The ALWAYS_INLINE doesn't have static on POSIX anyways since r178341; the INLINE is only used in .h files, so shouldn't have been 'static' in the first place

This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

llvm-svn: 179054

Add a regression test for the case where such behavior helps TSan:
  1. race is reported in the main module
  2. new shared library is loaded
  3. race is reported in the shared library
